Understanding Model Meaning:

 

Performance Characteristics Unveiled:

1. Cutting-Edge Winding Structure:
Engineered with a high-voltage winding that features a multi-layer cylindrical, continuous or connecting continuous design. This advanced structure enhances shock distribution, minimizes magnetic leakage, and provides exceptional mechanical strength and robustness against short-circuits.

2. Innovative Iron Core Design:
High-quality cold rolled grain-oriented silicon steel sheets are employed with a full diagonal seam stacking technique, significantly reducing both no-load loss and no-load current for greater efficiency.

3. Enhanced Fastening and Anti-Loosening Features:
Each core and winding is fortified with state-of-the-art fastening techniques. Components such as the high and low voltage leads are secured with self-locking anti-loosening nuts, and the non-hanging center structure ensures resilience against transportation vibrations. All fasteners are equipped with nuts to guarantee unwavering stability during extended operational periods.

4. Superior Vacuum Processing Technology:
Utilizing vacuum drying for coils and cores, alongside vacuum filtration and injection of transformer oil, this meticulous process significantly reduces moisture content within the transformer, enhancing its operational longevity.

5. Advanced Oil Tank Design:
Featuring a corrugated sheet oil tank with breathing capabilities to adjust for oil volume changes caused by temperature variations, this design eliminates the need for an oil storage cabinet, thus reducing the transformer's overall height.

6. Additional Distinctive Features:
Boasting an aesthetically pleasing and compact design, this transformer occupies minimal installation space, offering a maintenance-free solution ideal for diverse environments.
This versatile transformer is extensively employed across power plants, substations, industrial sectors, mining enterprises, and rural power grids, playing a critical role in power distribution systems.

 

Environmental Conditions and Requirements:
Ambient Temperature Specifications: The standard operational ambient temperature range is between -25°C and +40°C.
Altitude Limitations: Suitable for installations at altitudes not exceeding 1000 meters.
Air Humidity Constraints: Ensure the environment maintains a relative humidity not exceeding 90% at +25ºC.
Ideal Installation Sites: Select locations devoid of corrosive gases and noticeable dirt for optimal performance and longevity.

 

Maintenance and Upkeep Strategy:
Regular Inspection Protocols: Conduct frequent evaluations of oil levels and insulation strength. Promptly replace transformer oil when anomalies are detected to maintain peak performance.
Ensuring Stable Operations: Prioritize stable transformer operation by avoiding overloads and short circuits. Adhere to technical guidelines to avert operational abnormalities.
Safety Precautions and Considerations: Pre-installation planning should factor in adequate ventilation and fire prevention measures, aligning with technical specifications to ensure proper and safe installation.
